DD8 fall reading MAP is back and her score is lower than it was in fall of second grade. Yes she went from 98th percentile to 71st.
Do you have the scaled scores in addition to the percentiles? Did that drop too?
My dd was tested on the MAP reading 3 times last year (6th grade), fall, winter and spring. Her scaled score was highest in the fall and lowest in the spring. My theory is that her fall score was so high (I watched her teacher gasp when she looked at the report) that fluctuations are bigger. Also, the novelty for dd was probably wearing off after the first test in fall.
